Ethernet Encapsulation and De-encapsulation
Ethernet encapsulation describes the process by which an 802.11 MPDU wraps a full Ethernet frame for transmission while Ethernet de-encapsulation describes the reverse. The 802.11-2012 standard describes this process in Annex P, "the Integration Function." The process is slightly different depending whether the device performing the action is an access point or station.
